It's not a problem. What else would I do with them? I'm still working on Tsung's collection of books and other material.
To give you an idea: they take up the whole library. So I've an entire basement full of books that were probably never read in the first place, judging from the amount of dust that had collected on them.
At least this way I know they'll be put to good use, you might even find something useful and/or interesting.
